Study of Nanochitosan (Definition, Manufacture, Analysis of Characteristics and Utilization): Review

Nanochitosan is a nanoparticle of chitosan with size between 100-400 nm. has higher antibacterial ability than ordinary chitosan. The manufacture into nanochitosan can be done by ionic gelation method, namely the complexation polyelectrolyte positively charged and negatively sodium tripolyphosphate. morphology in form whole sphere typical functional groups such as amine, hydroxyl carboxyl groups. Utilization used natural preservative because it properties edible coating. Fish filets coated coating extend shelf life maintain freshness which seen from physiochemical characteristics.
